Pipe fittings

Abstract

The purpose of this invention is to provide a pipe fitting that can connect pipes of various sizes and exhibits excellent performance in assembly and practicality. The problem is solved by a pipe fitting for connecting pipes, characterized by comprising: a threaded connector disposed along the insertion space of the aforementioned pipe; two sleeves formed along the outer circumferential surface of the threaded connector, capable of being installed to surround the outer circumference of the aforementioned insertion space of the aforementioned pipe and deformable in the radial direction; the two sleeves being a large-diameter sleeve and a small-diameter sleeve; and a nut disposed on the outside of the two sleeves for covering the outer surface of the sleeves in the circumferential direction and tightening them; the threaded connector has a large-diameter sleeve portion for installing a large-diameter pipe on its root side outer circumferential surface, and a small-diameter sleeve portion for installing a small-diameter pipe on its front side outer circumferential surface; depending on the size of the pipe to be connected, either only one sleeve can be installed, or two sleeves can be installed consecutively in the insertion direction. none
